IMPROVEMENT IN ELEVATED-OVEN COOKING-STOVES.

Specification forming part of Letteis Patent No. 203,546, dated May 14,1878 application filed April 18, 18,78.

To all whom it may concern:

Be it known that I, JOSIAH JEwETT, of the city of Buffalo, in the countyof Erie and State of New York, have invented a new and Improved Methodof Constructing the Oven and Flues designed for what are known aselevated-oven cooking-stoves, of which the following is a specification:

The nature of my invention consists in providing three separate fluesthecenter flue to serve as the exit-flue of the stove, the side flues to beused when it is desired to heat the oven for baking-and combining withflues so arranged an elevated oven constructed so that the products ofcombustion passing through the side fines are taken up through openingsprovided for that purpose, thence upward in one sheet, and passing inlike manner over the oven-top, and downward to and through an opening oropenings into the exit-flue.

If the openings for the upward passage are located at the front of theoven the products of combustion in the downward passage pass throughopenings into the side flues, thence forward to and through openingsinto the exitflue, producing the same result.

By thus constructing the oven I utilize the bottom plate of the oven asthe upper wall of the three flues, and so insure a quicker and more evenand economical method of heating the oven than by making the bottom ofthe oven a separate plate placed above the plate covering the flue, asin ordinary stoves of this class.

Of the annexed drawings, Figure l is a perspective view of a sufficientportion of a stove .of the kind alluded to to illustrate my improvement.Fig. 2 is a perspective view, showing the arrangement of fines andopenings in the division-strips necessitated by the arrangement of thebottom oven-plate with the openings at the front of the oven instead ofat the rear. Figs. 3 and 4 are plans of the oven-bottom, illustrating,both positions of flue-openings. Fig. 5 is a longitudinal section ofthe stove, showing the oven in its proper position.

Like letters refer to like parts.

When the damper F is closed, as shown by the dotted lines, the openingsA A, Fig. 3, allow the products of combustion to pass from the two sideflues E E upward and around the oven and downward through the opening Ginto the exit-flue D to the pipe H, thus evenly and completelyencirclingand serving to thoroughly heat the oven. When the damper F -isopened, as shown in drawings, the products of combustion at once enterthe exit-flue D, passing off at the pipe H.

If desired, the oven-bottom may be constructed as shown in Fig. 4, sothat the products of combustion may -be caused to pass upward throughthe openings 0. 01/, around the oven, and downward through the openingsa" a into the side flues EB, and thence through the openings I I intothe exit-flue D, to the pipe H, as shown in Fig. 2.

What I claim as my invention, and desire to secure by Letters Patent, is

The bottom oven-plate G, provided with the openings A A and O, incombination with the side flues E E and the exit-flue D, the said bottomoven-plate forming the upper wall of the said fines, substantially asset forth and described.
